Bilateral Recession or Unilateral Recession-Resection as Surgery for Infantile Esotropia

This study has been completed.

Last verified: September 2005
History: No changes posted
Infantile esotropia is corrected in most cases by bilateral recession of the medial rectus muscles (BR) or by unilateral recession of the medial rectus muscle and resection of the lateral rectus muscle (RR). We compared the outcome of these techniques in a randomized prospective study.

Condition Intervention Phase
Strabismus Procedure: Bilateral recession Procedure: Unilateral recession and resection Phase 3

Study Type: Observational
Study Design: Observational Model: Defined Population
Time Perspective: Longitudinal
Time Perspective: Prospective
Official Title: A Randomized Comparison of Bilateral Recession With Unilateral Recession-Resection as Surgery for Infantile Esotropia

Study Start Date: January 1998
Estimated Study Completion Date: December 2001
Detailed Description:
We randomly assigned 124 patients (average age 5.8) from twelve participating clinics in Germany and the Netherlands to either BR or RR. Patients did not have demonstrable binocular vision at baseline. The angle of strabismus was measured pre- and postoperatively in a standardized fashion. The primary parameter to assess difference between BR and RR was the variation of the latent angle of strabismus at distance at three months postoperatively, secondary outcomes were reduction of convergence excess and binocular vision.

Ages Eligible for Study:   3 Years to 8 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Eligible were all children aged three to eight years with a normal psychophysical development, and onset of esotropia before age one who visited one of the clinics during the study period.

Exclusion Criteria:

  • previous strabismus surgery, an angle of strabismus larger than 24° or smaller than 10°, any normal binocular vision, convergence excess with angle of strabismus at near fixation 1.5 times larger than the angle at distance, more than 1 line Logmar acuity difference between the two eyes, hypermetropia over 6 diopters or myopia over 3 diopters, up- or downshoot in (25°) adduction more than 8°, V-pattern (25° up and down gaze) over 8°, A-pattern (25° up and down gaze) over 5° and manifest vertical strabismus over 4°
